Detachment Predatory: characteristics, representatives, features of life activity
The Predatory team unites representatives of the classMammals, consuming mostly animal food. The wolf and the fox, the tiger and the lion, the marten and the badger - these animals are known to everyone. This is not surprising, because predators have adapted to dwelling on all continents, except the coldest - Antarctica. Let's look briefly at what information on these animals biology has collected so far.
Order of Predators
First of all, they are united by the nature of food. It is not just of animal origin. All representatives of the Predatory detachment themselves attack their victims, killing them. Some of them feed on carrion, thus cleaning up habitats from decaying organic remains.
The main characteristic of the order of the Predatory is connectedit is with the features of the structure that allow them to hunt. Therefore, they all have a developed brain, a strong trained body, well-developed differentiated teeth. Particularly prominent are the fangs that they grab and tear the prey. On each side, one molar tooth is modified into so-called predatory ones. With their help, it is even possible to split large bones and sever strong tendons - it is so sharp.
From other mammals predatory is also distinguished by a highly developed nervous system, especially the brain. This determines the complex forms of behavior of these animals.
Predatory are quite diverse and number about 240 species. Therefore, a number of families are singled out in this detachment.
The Wolf family
Characterizing the squad Predatory (mammals), beforeall mention the family, received its name due to the tireless orderly of the forest. We are talking about the wolf and its relatives: fox, jackal, arctic fox, raccoon and domestic dogs.
They all have medium sizes and fairly long limbs. The structure of the musculoskeletal system and the muscular system allows them to pursue their future prey long and tirelessly.
The strongest and most agile among the representativesThis group is a wolf. Animals prefer to live in large flocks, the number of individuals in which reaches forty. Wolves are not only beautiful hunters, but also dangerous predators, which can attack even a person. They are rightly considered to be the orderlies of the forests, eating a large amount of carrion.
But the fox can not only eat animalsfood. Her favorite delicacy is the sweet and juicy fruits of forest plants. Foxes live in pairs or whole families. Man especially appreciates the beautiful, warm and fluffy fur of these animals.
We continue to study the Predatory detachment by example ... home cat. What kind of predator is this? The most real! His ancestor is a wild wild cat. And modern pets are the result of their domestication.
Basically, the same representatives of the family Catunite large body sizes with elongated limbs that end with retracted sharp claws. Everyone saw how a cat hunts for a mouse? She is not catching up, but is stalking her prey. The same behavior is typical for larger cats: a tiger, a lynx, a lion.
Most representatives of this familylives in the tropical and subtropical climatic zone of our planet. But the Amur tiger is the owner of the taiga of the Far East. It is one of the largest predators, by mass inferior only to the polar bear. Within the range of his range, he always occupies a dominant position. This applies to the links of food chains, because tigers hunt other predators, for example wolves.
Wonders of breeding
Since the lion and the tiger are the brightestrepresentatives of the entire animal world of the planet, genetic scientists have tried to create their hybrids. This experiment was completed quite successfully, because as a result of crossing, viable individuals obtained new properties as compared to the original forms. So, the liger - a hybrid of a lion and a tigress, is capable of unlimited growth. In nature, this feature is characteristic of plants and fungi. The liger grows throughout life, sometimes reaching a length of up to 3 meters.
Typically, interspecies hybrids are not able to giveprolific offspring. Tigrolov is an exception to this rule. This is practically the only case in breeding. Female, obtained by crossing a tiger and a lioness, are capable of procreation.
We continue to consider the Predatorymammals on the example of a family that unites individuals with valuable fur fur. Otter, marten, ermine, mink, ferret - that's not a complete list of representatives of the family Kunya. Many of them perfectly climb trees, and otters are excellent swimmers. Another badman is a badger. He is particularly valued meat, which is used for food, and fat, which has medicinal properties.
The Bear family
The Predatory detachment has mastered all the climatic zones. Its representatives can be found even in the cold expanses of the Arctic. It is there that the largest representative of predatory mammals lives - a polar bear, the mass of which can reach 750 kg. He swims beautifully, hunting for fish and pinnipeds.
But in the woods the Predatory detachment represents anotherthe beast is a brown bear. He can eat both plant and animal food, attacking deer or wild boar. In winter, this species of bears hibernates, and in summer leads an active lifestyle. He is an object of hunting due to valuable meat and skin.
The Predatory group unites a number of families of the classMammals, whose diet is dominated by animal food. These animals are well developed sharp teeth for hunting. Many species are valued by man because of valuable fur, meat and fat. Therefore, at present many species of carnivorous mammals need protection.
